Question

Newton’s third law of motion explains the two forces namely ‘action’ and ‘reaction’ coming into action when the two bodies in contact with each other.These two forces:

• A. always act on the same body.
• B. always act on different bodies in opposite directions.
• C. have the same magnitude and direction.
• D. always act on different bodies in the same direction.

Answer 1

The correct option is B always act on different bodies in opposite directions.

According to Newton's third law of motion, for every action there is an equal and opposite reaction. But these two forces act on two different objects and not on the same object. If these two forces being equal in magnitude acted on the same body, they would cancel out each other and the resultant would be zero.
